HINGE.

Specification of Letters Patent.

Application filed December 27, 1910. Serial No. 599,438.

Patented Sept. 26, 1911.

To all whom it may concern: j

Be it known that I, ISAAC H. WAT'IERS, a citizen of the United States,and a resident of Galesburg, in the county of Knox and State ofIllinois, have invented a new and useful Hinge, of which the followingis a specification.

The invention relates particularly to leaf or strap hinges, andespecially to that type thereof which are commonly employed on doors.

In the use of hinges of ordinary constructions it has been impossible toso separate the respective butts that, after withdrawal of the pintle,the door-butt could be drawn directly past the jamb-butt, whereby thedoor could be released from the hinge side thereof while the bolt of thelock was engaged with its keeper. In such hinges as are separable whilethe butts are positioned as in use (and when the door is closed,) theknuckles have been so disposed with reference to the leaf portion that agreat, unsightly gap was created between the door and the door-post, orthe casing. Furthermore, the Yknuckles were at such distance y from thepoints ofsecurement to the door and casing that the weight of the formerand the resultant Ileverage would cause the screws to become loosenedfrom the casing. The door would not, therefore, freely swing to itsvclosed position, but would sag and strike the floor, thethreshold-board, and the other casing. The oifset portion and knucklesprojected to such an extent that it was unsightly andV whollyincongruous with artistic environments, such as are provided in thebetter class of residences, hotels, offices, etc. The free edge of thedoor was thrown a great distance from the pivotal point, thus preventingit being swung back f against the wall when the hinge-j amb is locatedonly a slightly greater distance from the wall `which 1sV disposed at aright angle to the door than is the width of the door.

The primary object of my invention is to provide a hinge Iof suchconstruction that the door-butt may, from the lock side only, beseparated from and slipped past the jamie-butt, whereby the door may beopened without picking `or breaking the lock and without injury toeither the door, the casing, or the lock, of theiobjectionable featuresabove noted.

Another object is to provide a more ornate and attractive hinge (whenpositioned) than has heretofore been presented.

Minor objects will be in part obvious and in part pointed out.

In the accompanying' drawings, which illustrate the best exempliicationof my improvements now known to me :wFigure l is and which hinge will bedevoid a transverse sectional view, taken just above the lock, the doorshown in locked position, but the pintle withdrawn. In this position theparts occupy such relative positions that the door may be opened fromthe hinge side. Fig. 2, is a similar view, the plane of section beingjust above the upper hinge, and the door shown as swung from the hingeside; Fig. 3, a fragmental sectional view, taken just above eitherhinge; Fig. 4, a front elevation illustrating the manner of sliding thej door-butt fimm the j amb-butt, the arrow indicating the direction ofmovement; Fig. 5, an elevation of the hinge as it appears when removedfrom the door and jamb, the rear surface or back of the jamb-butt beingseen; Fig. 6, a fragmental detail, the butts being separated and placed,the l jamb-butt above its companion, to illustrate the relative sizes;FigQ, a bottom plan, the butts separated as in operation; and Fig. 8, a

front elevation, the parts appearing as if seen from within a room andas in the same position on a door as is shown in Fig. 1. Figs. 4 to 8inclusive are enlarged with vreference to Figs. 1, 2, and 3.

In all the figures of the drawing the same i i the plane face of theleaf 3, and are offset therefrom, whereby no portion of the knuckle liesin line with the plane "of the face of the leaf. (On hinges asordinarily constructed, the knuckle is notoffset from the plane of theface of the butt, but is directly in line with the plane cf the face andback thereof and projecting to both sides thereof.) The face of eachleaf is that lane surface thereof which is opposed to the other leafwhen said leaves are substantially parallel, as when the door is closed.Both the upper and lower knuckles are internally threaded as shown at 7,Fig. 4, to selectively receive an ornamentally-headed hinge-tip 9 whichin use is threaded into the lower eye.

10 indicates a jamb-butt, comprising a strap or leaf 11 slightlynarrower than the leaf 3 and provided with countersunk screwreceivingapertures 12. Its exposed edge is continued Vand immediately curved orturned to form offset, registering, spaced knuckles 13, these bearingthe proper numerical and placement relationship to the number andpositions of the knuckles 4. The knuckles 13 are disposed entirely inrear of the plane of the face of the leaf 11; in other words, no part ofthe knuckle projects forwardly of the plane face of the leaf, and theedge of the knuckle lies or rests against or substantiallyagainst thatportion of the leaf which parallels the jamb. It will be seen that noportion of the knuckle (which provides the pintle-receiving eye) liesforwardly of the face-line cf any plane portion of the butt 10. In orderto provide a close -fit, the exposed edges of the leaf 11 are beveled atboth top and bottom and also between the spaced knuckles 13, whichspaces are provided by omitting portions in an evident 'mannen When thebutts are brought into the closed position shown best at Fig. 1, theleaves 3 and 11 will lie substantially parallel, with the eyes of theknuckles 4 and 13 registering and both of them offset in the samedirection. The curved portion of the door-butt is, however, slightlylarger than the similar portion of the jamb-butt in order to preserveproper mechanical proportions.

15 is a pintle, provided with an ornamen` tal head.- Its stem isslightly less in diameter than the diameter of the openings in theknuckles, in order that it may be freely passed therethrough from eitherend of the hinge. By turning the hinge upside down and reversing thepositions of the screw 9 and pintle, the one shown serves with equalfacility as a left hand hinge.

In order to clearly illustrate the operation, reference is to be hadparticularly to Figs. 1 and 2, and to some extent to Figs. 3, 4 and 3.In Figs. 1, 2 and 3, 19 indicates what I shall for the purposes hereofterm the hinge-jamb, and 20 represents the lockj amb, which latter isprovided with a recess or mortise 21 adapted for the reception of thebolt 22 of a mortise lock 23 (diagrammatically shown) suitably securedin a door 24.

25 indicates portions of the casing, 26 the stops, 27 the threshold, and28 indicates a fragment of the wall, as shown at Fig. 3.

Assume the parts to be in the relative positions shown in Fig. 1,wherein the bolt 22 is engaged with the mortise 21 and the pintlewithdrawn from the knuckles 4 and 13. By drawing on the knuckles 4 theoperator will cause them to move out from the spaces between theknuckles 13, and the face of the leaf 3 will slip or wipe past the faceof the leaf 11, inasmuch as no portion of i the knuckle of the jamb-buttprojects inwardly (with reference to the roem) of the proximal edge ofthe hinge butt, as it does in hinges where the knuckle is disposed inline with, or approximately in line with, the ed'ge of the j amb-butt.'Ihe operation just described is best shown at Figs. 2, 4, and 8. Uponits completion the door may be drawn in the direction of the arrow atFig. 2 to free the bolt 22 from the recess 21 in an evident manner,whereupon the lock may be removed from the door without injury toeither. No expense will have been incurred; neither will the casing northe jamb have been mutilated. Even though the door be swung entirelyback, it will neither mutilate nor be mutilated by the adjacent casingboard 25, being held distant therefrom as shown in Fig. 3. However, theinner edge of the door will not be thrown an extreme distance from thecasing, to provide the wide gap earlier herein referred to. Neither willthe free edge be thrown a great distance from the pivot or the casing.There will be no unsightly extension projecting over the casing. Theleverage is practically eliminated, whereby danger of sagging ispractically obviated. The curves of the knuckles present an ornate andattractive appearance to the eye, and it will be seen from an inspectionof Fig. 1 that they project inwardly of neither the jamb-leaf nor thehinge-jamb. The manner of opening the door from the lock side isindicated by the arrow at Fig. 1.

It has not been thought necessary or best to encumber this specificationand the draw*- ings with illustrations of modifications which areneitheressential to nor form any part of the invention herein claimed. In fact,it is apparent without such, that changes may be made in the details ofconstruction and by modifications involving only mechanical skill,without departing y cure by Letters Patent the following, In Witnesswhereof I hereunto aiix my 1o to-Wit:- signature at Galesburg, in thecounty and A hinge comprising a pair of leaves, State above Written,this 20 day of Decemknuokles projecting from one edge of each ber, 1910.leaf and entirely on one side of the plane oi' ISAAC H.
